Can piecewise functions be differentiable

WebThere are everywhere differentiable functions with discontinuous derivatives, so unless "piecewise differentiable" adds further regularity, you won't be able to prove it. – Daniel Fischer Feb 23, 2016 at 16:48 Thanks for the pointer. I mean that f is continuously differentiable at all but a finite number of points. WebFeb 17, 2024 · So for differentiability of the function at $x=1$, we must have both $$a+b=e\tag1$$ $$1+2a+b=e\tag2$$ Solving this, we have $a=-1$ and $b=e+1$. So the function will be differentiable only for $a=-1$ and $b=e+1$. Hence, the option $(2.)$ is …

WebSep 7, 2024 · Let f be a function. The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h.

I wonder why we cannot solve the following problem as follows: If f is differentiable everywhere, then it is continuous everywhere, so it must be b = 4 – 2 m. Also m = 2 x at x = 2 (taking derivative of each of the pieces).

WebAt x = 1, the composite function f (g (x)) takes a value of 6 . At x = 1, the slope of the tangent line to y = f (g (x)) is 2 . The limit of f (g (x)) as x approaches 1 is 6 . Consider the … Weblim h → 0 h 2 sin ( 1 h) h. which happens to exist and equal 0. This is why f is differentiable there. (For instance, setting f ( x) = x if x is non-negative and f ( x) = − x if x is negative is differentiable everywhere except at 0, though both pieces are everywhere differentiable). Moreover, f is continuous at 0.
